Battery Replacement
How to Order
A low battery indication will be shown in the upper left-hand
corner of the display when the battery voltage falls sufficiently.
The batteries should be replaced soon after the indicator
comes on to prevent unreliable readings.
If unit does not power up, replace the batteries.
1. Loosen the 6 Phillips screws on the back of the unit until the
cover can be removed
2. Remove the battery cover and remove the batteries by lifting up the positive end of the battery (opposite the spring)
taking care not to bend the battery holder spring.
3.Discard old batteries properly, do not discard into fire,
sources of extreme heat, or in any hazardous manner.
4. Always replace both batteries at the same time with high
quality alkaline batteries. Install batteries with correct orientation. The negative (flat) end of each battery should be
inserted first facing the battery holder spring.
5. Replace the back cover, including the sealing gasket.
°F/°C, shutoff times and min/max functions are field configurable. If you require a certain configuration to be pre-set from
the factory, please indicate it on your order.

Cecomp ThermoPro® Battery Powered Temperature Indicator Instructions
Precautions
Read these instructions before installation. Configuration may
be easier before installation.
Install or remove thermometer using a wrench on the hex fitting
only. Do not attempt to turn by forcing the housing.
Do not exceed maximum allowable housing temperature.
The spring-loaded design must be used with a thermowell.
The fixed probe design can be used in applications with low or
no material flow. Due to the hardness of 316 stainless steel,
it is recommended that a thread sealant be used to ensure
leak-free operation.
Normal Operation
To turn the unit on, press the left front power button.
The display segments are tested.
The actual temperature and units are displayed and updated
approximately 4 times per second.
The factory default configuration is °F, 5 minute auto shutoff
and MAX/MIN disabled.
The auto shutoff timer is reset whenever any button is pressed.
To shut off the unit manually at any time, press and hold the
power button until OFF is displayed (up to about 5 seconds
total if MAX/MIN is enabled) and then release the button.
If the unit is configured with an auto shutoff time, a five second
warning period is provided prior to auto shutoff, during which
the display indicates OFF. Press any button to reset timer.
If so equipped, the optional display backlighting can be turned
on by momentarily pressing a button whenever the thermometer is on. The backlighting will turn on for one minute and then
automatically shut off. This also restarts the auto shutoff timer.
The display backlighting will not be apparent under bright
lighting conditions.
Temperature Unit Selection
To change temperature units, press and hold the s (up) button
until the temperature indication is blank and only the temperature units are displayed.
Then use the s or t buttons to select the desired temperature
units. Standard units are Fahrenheit, Celsius, and Kelvin.
When the desired units are displayed, press and release the
power button to save the selection and exit the change mode.
If no buttons are pressed for 15 seconds, the unit will automatically save the selection and exit the change mode.
Auto Shutoff Time Selection
To change the auto shutoff time, press and hold the t (down)
button until the auto shutoff time is displayed.
The auto shutoff time is shown on the upper display. AST M
indicates auto shutoff time in minutes, and AST H in hours.
Use the s or t buttons to select 0, 1, 2, 5, 10, 15, 20, or 30
minutes, or 1, 2, 4, or 8 hours.
Setting the time to zero to disables the auto shutoff timer and
the thermometer will stay on until manually shut off or until
the batteries are depleted. Use the power button to turn the
thermometer off when not in use to conserve battery life.
When the desired auto shutoff time is displayed, press and
release the power button to save the selection and exit the
change mode.
If no buttons are pressed for 15 seconds, the unit will automatically save the selection and exit the change mode.
User Configuration Mode
With the unit off, press and hold the s button. Then press the
power button. Release buttons when the display indicates CFG.
Before the unit enters the Configuration Mode, the display
initially indicates _ _ _ _ with the first underscore blinking,
and with CFGPC on the character display.
Note: The unit will automatically revert to normal operation if no
buttons are operated for approximately 15 seconds. To cancel
and return to normal operation, press and release the power
button without entering any pass code numbers.
Enter the user configuration pass code (3510 factory default):
Use the s or t buttons to set the left-most digit to 3.
Press and release the power button to index to the next position. The 3 will remain, and the next position will be blinking.

Thermometers are normally configured with maximum and
minimum capture functions disabled. One or both can be
enabled in the User Configuration mode.
If enabled, step the unit through the display modes by pressing
the power button for about 1 second until the display indicates
either MAX or MIN or degree units. The display mode cycles
through the following steps:
MAX mode: The maximum temperature is shown with the
lower display alternating between MAX and the degree units.
The thermometer may be left in this mode if a display of the
maximum reading is desired.
MIN mode: The minimum temperature is shown with the lower
display alternating between MIN and the degree units. The
thermometer may be left in this mode if a display of the minimum reading is desired.
Normal mode: The current temperature and the degree units
are displayed.
To manually reset the memory, press and continue to hold the
power button until the display indicates clr (about 3 seconds
total) and then release the button. The stored maximum and
minimum values are cleared. The unit returns to normal operation with the display indicating the current temperature.
The memory may be configured to be automatically cleared
when the unit shuts down, or may be configured to retain the
maximum and minimum values at shutoff.
Calibration Mode
Select the temperature units for calibration prior to entering the
calibration mode. The use of Fahrenheit or Celsius is assumed
in this procedure.
To enter the calibration mode, begin with the unit powered off,
and press and hold the t button. Then press the power button.
